Problems solved by technology

[0020] However, in the actual environment, due to the large interference at the cell border, the signal transmission quality of the link drops rapidly, and the signal is likely to deteriorate rapidly during the handover time. talk phenomenon
In addition, because the handover threshold is fixed, the moving speed of the MS is different, and the link situation where the MS is located is also changing. Moreover, the handover process requires a certain time delay. When the handover is completed, the parameters of

Embodiment Construction

[0067] If it can be estimated in advance that the downlink signal transmission quality of the original serving cell of the mobile terminal will deteriorate rapidly, the handover process can be completed in advance by dynamically adjusting the decision threshold, so as to effectively avoid the rapid deterioration of the downlink signal transmission quality of the original cell during the handover process If the upward trend and stability of the downlink signal transmission quality of the adjacent cell of the mobile terminal can be estimated in advance, then the adjacent cell whose signal transmission quality is steadily increasing can be used as a candidate by dynamically adjusting the decision threshold The target cell is used to ensure the signal transmission quality of the serving cell of the mobile terminal after the handover is completed; thus, the success rate of handover can be effectively improved, and the utilization rate of system resources can be improved.

Abstract

A method for carrying out switching in radio mobile communication system includes obtaining signal transmission parameter value of mobile terminal and dynamically regulating decision threshold of switch when it is confirmed that said signal transmission parameter value is satisfied to preset condition, carrying out switch decision and switch course of mobile terminal according to regulated decision threshold of switch.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a switching method and system in a wireless mobile communication system. Background technique [0002] A wireless mobile communication system generally includes two basic components, BS (base station) and MS (mobile terminal). The mutual communication between the BS and the MS is not realized through a wired channel, but is realized in a wireless manner by transmitting and receiving electromagnetic waves through a wireless transceiver. Each wireless transceiver has a certain coverage area, if it exceeds this coverage area, the communication between BS and MS will be interrupted. [0003] A BS can communicate with multiple MSs within its coverage area. The signal sent by the BS to the MS is called a downlink signal, and the signal sent by the MS to the BS is called an uplink signal. The coverage of each BS is limited, but multiple BSs can form a wireless communicat...
